CD45-E2GA222M-NKA 产品概述

CD45-E2GA222M-NKA 是 TDK 推出的一款通过插件封装(引脚间距 P = 10 mm)的安规薄膜电容,容值为 2.2 nF,容差 ±20%。该器件同时满足 X1 与 Y1 防护等级要求,可在交流 400V 至 440V 工况下长期工作,适用温度范围宽 (-25 ℃ 至 +105 ℃),专为电源输入端的 EMI 抑制与安全隔离设计,适合家用电器与工业设备的抑制干扰与安全耦合场景。

一、主要参数概览

  • 品牌:TDK
  • 型号:CD45-E2GA222M-NKA
  • 容值:2.2 nF (222)
  • 容差:±20%
  • 额定工作电压(AC):400 V;440 V
  • 防护等级:X1, Y1(可用于跨线与线对地抑制)
  • 工作温度:-25 ℃ ~ +105 ℃
  • 封装形式:插件(引脚间距 P = 10 mm)
  • 典型用途:电网侧 EMI 滤波、跨线抑制、工频干扰抑制、脉冲吸收与安全耦合

二、产品特性与优势

  • 双重安规等级:同时具备 X1 与 Y1 功能,单颗器件在不同接法下可满足跨线(L–N)与线对地(L–PE/N–PE)两类安规要求,节省器件种类与库存。
  • 宽温度适应:-25 ℃ 至 +105 ℃ 的工作范围,适合多数家电与一般工业环境的长期工作。
  • 插件封装,易于手工焊接与波峰/选择性焊接,在混合装配或维修场景中使用方便。
  • 额定交流电压覆盖 400 V 至 440 V,适合 230 VAC(单相)与更高工况的三相或特殊电网环境。
  • 标称容值 2.2 nF 适合用于 EMI-L-C 滤波器的中等阻抗位置,同时能在不影响电源稳定的情况下有效衰减高频干扰。

三、典型应用场景

  • 输入 EMI 抑制电路(X 电容,跨 L–N)
  • 线对地抑制与安全耦合(Y 电容,用于 L–PE 或 N–PE)
  • 家用电器主板(电视、洗衣机、微波炉等)电源入口滤波
  • 开关电源与适配器的电网侧干扰抑制
  • 工业控制设备与医疗设备(非体内)电源安全设计中的噪声抑制(应结合系统认证要求)

四、设计与选型建议

  • X1 与 Y1 的正确选用:X1 用于跨线抑制(直接并联在 L 与 N 之间);Y1 用于线对地(L/N 对 PE)抑制。Y 类电容对人体安全有更严格要求,布置位置应尽量靠近输入端并保证单一接地路径。
  • 并联放电电阻:为保障维修与拆卸安全,建议在电源断电后并联一个合适阻值的放电电阻,确保电容在规定时间内放电至安全电压。
  • 考虑浪涌与脉冲:在含大量浪涌或尖峰干扰的场合(例如感性负载切换),建议在设计中加入浪涌吸收元件或更高峰值承受能力的抑制元件。
  • 温升与老化:尽量避免长期工作在最高温度及最大电压同时叠加的工况,适当留裕以延长使用寿命。
  • 并联与分配:若需更大容值或不同电压耐受,可采用多颗并联或分配在不同电路位置,但对 Y 类电容的并联需遵循安全规范与认证要求。

五、安装与使用注意事项

  • 焊接温度:遵循制造商关于焊接曲线的推荐,避免长时间高温导致电容参数漂移或老化。
  • 布局隔离:X/Y 电容应与低压信号电路保持适当距离,避免通过耦合引入干扰。
  • 极性与方向:此类薄膜安规电容为无极性,但在 Y 类连接时应注意与安全接地的正确连接方式。
  • 机械应力:插件元件应避免强烈拉扯或弯曲引脚,以免影响机械强度与电气间隙。

六、质量与认证

CD45-E2GA222M-NKA 作为安规电容,其 X1/Y1 标识表明器件设计用于抑制工频电网干扰并具备对应的安全特性。具体的认证(如 UL/VDE/EN 等)与试验数据请以 TDK 官方数据手册与认证证书为准,设计时建议索取并确认相关认证文件以满足终端系统的法规与行业标准要求。

七、典型电气性能与可靠性提示

  • 标称容值与公差:2.2 nF ±20%,在设计滤波网络时考虑容差对截止频率的影响。
  • 频率特性:适合工频与高频干扰抑制,但具体 ESR/ESL、负载损耗等请参考厂家完整电气特性曲线以便精确仿真。
  • 寿命与老化:在高温高压环境下,薄膜电容会有一定的参数漂移,推荐在关键可靠性场合进行加速老化测试或采用冗余设计。

八、包装与订购信息

  • 封装:插件式,P = 10 mm,引脚适配常见通孔 PCB。
  • 订购时请确认完整型号(含后缀)与批次,获取最新的库存与交货期信息。若需样品或大量采购,可直接联系 TDK 或其授权分销商获取技术支持与合格证书。

总结:CD45-E2GA222M-NKA 以其 X1/Y1 双重安规属性、2.2 nF 的典型容值与插件安装方式,为电源输入端的 EMI 抑制与安全耦合提供了可靠的解决方案。设计与使用中应重点考虑放电、安全接地、布局隔离与工作余量,以确保长期稳定与符合系统级安全规范。若需要更详细的电气参数表、浪涌承受能力或认证文件,建议向 TDK 索取官方数据手册。

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
